I see the importance of finding a suitable alternative to maintain your business workflows effectively, Sales317.
While we’re unable to recommend a specific or alternative connector, we suggest exploring the QuickBooks Online Apps, which include various integration tools tailored to your business needs. These apps can help you connect QuickBooks with e-commerce platforms and streamline your processes.
To start your search, visit the QuickBooks Apps page or access it directly in your QuickBooks account. For your convenience, I’ve included a visual guide in the screenshot below, which shows how to navigate the apps marketplace.

When considering an alternative connector, I recommend reviewing app descriptions, user ratings, integration features, and pricing options to ensure it aligns with your workflow requirements.
If you want to know what apps are supported by Intuit and how to get support when needed, you can read and review this article: Apps that work with QuickBooks Online.
